The blue colour of copper sulphate is due to water of hydration. invertebrates where death may be difficult to determine. replace or supersede the restrictions, precautions, directions, or They should therefore conclude that the same quantity of energy is absorbed when the endothermic thermal decomposition takes place. Researchers exposed juvenile rainbow trout (. Algaecide. of their life with no appreciable risk of adverse health effects. Using mass of substance, M, and amount in moles. 113 days. which in turn is affected by pH, redox potential, dissolved organic carbon, and ligands present in the soil. The copper ions present in copper sulfate react with the chloride ions belonging to concentrated hydrochloric acid, leading to the formation of tetrachlorocuprate(II).
